The Importance of HVAC Maintenance
Maintenance is crucial when it comes to cooling and heating systems. It will allow you to avoid costly repairs or premature replacement. The majority of HVAC companies offer a maintenance plan that charges the monthly cost to get the system checked, fixed or cleaned when necessary.
You should also carry out some DIY maintenance throughout the year. These include cleaning or replacing air filters and keeping the areas around outdoor units clear of debris to promote the proper airflow.
Clean the Condenser
The coils in your condenser for your air conditioner are at the heart the cooling process. If they are dirty, your system will struggle to cool and could even breakdown. This is why cleaning them is a vital aspect of HVAC maintenance. It’s also quite simple to do. This easy DIY task will save you money, avoid expensive repairs and extend the lifespan of your air conditioner.
In the beginning, it is crucial to shut off the power supply to your unit. This can be accomplished by turning off the breaker inside your electrical box or at the outdoor unit disconnect switch. This will protect your electrical components and motors from being flooded when cleaning.
After the power has been turned off, you can begin taking down any large objects that could be hindering the air condenser. This includes sweeping away any leaves, sticks or other debris that have built up on or around the unit. A shop vacuum equipped with a crevice tool is an excellent way to reach into the nooks and crannies and remove dust or dirt that has accumulated.
The coils must be cleaned. Be sure to have a few essential tools available before you start. This will include a concentrate for coil cleaning and a pump-up garden hose and a garden hose. Spray the coil cleaner according to the instructions on the label, and then rinse it off using a hose. When washing the coils it is essential not to use excessive force since the fins can bend easily.
After the coils have been cleaned, you should inspect them for any signs of damage. Over time, the impact of hail and stones dropped by lawnmowers or other items could damage the coil fins. If the fins are bent, an affordable tool known as a fin-comb can straighten them for better air flow and to aid in the operation of the coils more effectively.
When you have a great coil and fin set up and you are ready to switch on your air conditioner. After around 24 hours, you should check the thermostat to ensure that temperatures are normal.
Clean the Ductwork
Your HVAC system works by bringing air from outside, cooling it and distributing it throughout the home. The air moves from the evaporator coil of the condenser unit to your home’s vents and registers through a system of ducts. These ducts may become clogged with dust and other pollutants when they aren’t cleaned and sealed correctly. This could block air filters which reduces the effectiveness of your system and burdens your AC unit.
In the majority of instances, cleaning ductwork is not an easy job and requires professional equipment and methods. There are a few things you can do regularly to keep your ducts clean and in good working order. First, you should change your filter regularly to prevent dust and allergens out of building in the ducts. This will also help prevent clogging, which can lead to a reduced system efficiency and a higher cost for energy.
Another way to help keep your ducts clean is by regularly cleaning the area around the vent openings. Utilizing the hose attachment of your vacuum cleaner, you can get rid of all of the cobwebs and crumbs which accumulate over time, and will assist in improving airflow through the vent. Also, make sure that your ducts have been sealed tight and insulated to prevent moisture from getting in, which could result in mold and other biological contaminants.
Ducts that have not been cleaned on a regular basis can become loaded with a wide variety of contaminants, including dust, pet dander, and pollen. These particles can cause respiratory and allergy conditions, particularly for children and the elderly. Moisture can cause mold to develop in ductwork, which releases the spores that can be harmful to those with respiratory problems.
It’s generally recommended that you have your ducts cleaned every three to five years to eliminate these contaminates and ensure that your HVAC system is operating effectively. If your ducts have been sealed well and you regularly change your filter It may not be necessary to clean them. The best way to know the truth is to have your ducts tested. An accredited contractor can use special testing methods to gauge the amount of dust particles in your ductwork, and will recommend the suitable cleaning schedules based upon your specific situation.
Check the Compressor
The compressor is a crucial element of the system. It must function properly to deliver cool air to the ducts. If the compressor isn’t functioning in the way it should, this could affect your productivity and result in interruption to your equipment. Regular maintenance can help you identify minor issues early, preventing unnecessary downtime. These regular checks will also save you money by making sure that your equipment as efficient as possible.
A reduction in cooling capacity is a typical sign of a problem in the compressor. It could be caused by several different reasons. One possibility is that a compressor may be working too hard due to poor airflow. This can cause bearings to wear down and decrease the life of the compressor. Another issue that is common is a blocked filter. Filters that are clogged can restrict airflow and cause the compressor to overheat. It is crucial to clean or change the filters according to manufacturer’s instructions.
A blocked filter could cause a sound of rattling in the compressor. This could be a sign that the bearings need to be replaced. It is recommended to replace belts and pulleys regularly. A worn belt or pulley could cause slipping and result in compressor overheating and other issues. It is also a good idea to drain the compressor on a regular basis. This will help remove moisture that could cause corrosion to the motor and other components. A professional service team will also look for air leaks in the hoses and an adequate seal between the compressor and the pressure switch.
A small puddle of water around the compressor could be an indication of a leak in the refrigerant. This could be a risky problem and needs to be fixed right away. If you suspect there is a leak, switch off the compressor that is running and then contact a professional.
Check the Thermostat
The thermostat is kind of like the head of your HVAC system, so it’s not a surprise that it’s the first thing a technician will inspect when a problem occurs. A properly maintained thermostat is essential for the proper operation of your HVAC system. It’s one of the most neglected maintenance items. Check your thermostat if observe inaccurate temperature readings, unresponsive controls or constant cycling.
Inaccurate Temperature Readings
Over time the sensors on your thermostat can become dirty. This can cause it to display incorrectly. You can avoid these problems by ensuring the accuracy of your thermostat with a separate thermometer.
A malfunctioning sensor or calibration could lead to your system continuously turning on and off that is known as short cycling. This can affect your comfort and cause excessive wear and tear on the compressor. These issues can be resolved by replacing the batteries in the thermostat or resetting the breakers.
If your thermostat isn’t responding to your thermostat in any way it’s an excellent idea to look at the breakers that regulate the thermostat as well as your HVAC equipment. If the breaker tripped then you’ll have to reset it in order for your thermostat to communicate again with the system.
Examine your thermostat for signs of wear and tear. Check for dirt or dust and ensure that the thermostat isn’t overly exposed to the sun. Check the fan blades for signs of damage and rust. This simple check will help avoid costly repairs in the future, and ensure that your equipment is running as smoothly as possible.
Basic hvac maintenance is a great method to save energy and maintain comfort in your commercial building. It can also prolong the life of your cooling and heating equipment. By identifying any issues with your thermostat, setting the breaker, and replacing the batteries, you’ll be able to keep your building warm all year round. Just remember that in case you experience any other issues or aren’t sure what’s wrong with your system you should always consult a professional.
